Become an Amazon OpenSearch SME in 30 Days
The most comprehensive OpenSearch learning platform built for AWS engineers — structured notes, scenarios from Indian digital commerce, quizzes, diagrams, and operator-ready cheat sheets.
Everything you need to own OpenSearch in production
From inverted indexes to FGAC, OSIS pipelines to k-NN hybrid search — connected into one learning system.
Interactive 30-day roadmap
Four phases from foundations to capstone design, with local progress tracking and phase celebrations.
Deep theory notes
Nine exhaustive chapters with Query DSL, security, ingestion, k-NN, pricing, and Indian business analogies.
Real-world Indian scenarios
Flipkart search, Swiggy geo, Zomato logs, Razorpay fraud signals — architecture and trade-offs spelled out.
Self-assessment quiz engine
100+ questions across modes: quick, full exam, phase drill-down, and topic retries with weak-area links.
Architecture diagram gallery
Twenty Mermaid diagrams covering VPC, ISM, OSIS, hybrid search, blue/green, and SME reference stacks.
Printable cheat sheets
Dense operator reference: node types, ISM templates, FGAC, metrics, limits — optimized for A4/Letter print.
This hub is designed around evidence-backed learning: retrieval practice through quizzes, spaced repetition via the 30-day roadmap, and the Feynman technique — explain Flipkart search or IRCTC logs as if teaching a teammate — reinforced by scenarios and diagrams.
Read deeply, draw architectures, then test yourself. Repeat on weak topics until OpenSearch internals feel obvious.
